Description
Technical field
The utility model relates to a kind of operational system, the operational system of especially a kind of drive motor and vacuum pump.
Background technology
Electronlmobil, as energy-conservation, free of contamination ideal " zero-emission " vehicle, is just being subject to common concern and the attention of countries in the world.The New-energy electric vehicle industry of China is subject to the encouragement of national policy just in healthy and strong growth.
At present, in China's pure electric automobile field, the brake vacuum force aid system vacuum occurring source overwhelming majority is independent electric vacuum pump, and in vacuum booster assembly, the degree of vacuum negative pressure of common pressure chamber reaches the general 0.05 ~ 0.07MPa of requirement.Its vacuum boost system basic structure, vacuum pump connects vacuum air storage tank by vacuum hose, and vacuum air storage tank connects vacuum booster and by the pressure switch connection control device on storage tank, vacuum booster connects brake pedal unit.Independently electric vacuum pump has and mainly contains now two kinds: vane-type vacuum pump time a kind of, and its merits and faults has vibrations little, and assembly volume, weight are little, and operating noise is larger; Piston type vacuum pump work merits and faults has: operating noise is less, and vibrations are comparatively large, and assembly volume, weight are larger.Considerable influence is had above to the comfort level of vehicle.
Independently electric vacuum pump during domestic braking of battery electric vehicle vacuum generating system vacuum occurring source, vacuum brake basic structure is as shown in Figure 1;
The groundwork of this vacuum generating system: principle is when chaufeur starts automobile, 12V power connection, pressure sensor and the self-inspection of pressure warning unit initiation pressure, if the degree of vacuum in vacuum reservoir is less than 55kPa, pressure-sensitive diaphragm will extrude contact, thus switches on power, and vacuum pump is started working; When degree of vacuum is increased to 55kPa, pressure time delay switch disconnects, and then by slug relay, vacuum pump is worked on after about 30s and stops; When each chaufeur has a braking maneuver, pressure time delay switch all can self-inspection, thus judges whether electric vacuum pump should work; If the low vacuum in slack tank is when 34kPa, vacuum booster can not provide actv. vacuum servo, and now pressure warning unit will send signal; This kind of complex structure, productive costs is high, and installation effectiveness is low, therefore, being just badly in need of developing and a kind ofly can reducing productive costs and the operational system of drive motor easy for installation and vacuum pump, through retrieving, not finding the same or analogous technical scheme with the utility model.
